o-na [289]

Answer:

A. 8%

B. 39.6%

C. 58.4%

D. 41.6%

Step-by-step explanation:

Computation to determine the probability of eligible voter selected at random

First step is to Draw up a contingincy table which will include Rows = Degree/No degree

and Columns= Vote/Not vote

..............Vote..No vote

Degree 80...20...100

(80%*100=80)

(100-80=20)

No Degree 504..396..900

(1000-100=900)

(56%*900=504)

(504-900=396

Totals 584..416...1000

(80+504=584)

(20+396=416)

(900+100=1,000)

Summary

..............Vote..No vote

Degree 80...20...100

No Degree 504..396..900

Total Totals 584..416...1000

A. Calculation to determine the probability of The voter had a college degree and voted in the last presidential election.

P = 80/1,000

P=0.08*100

P=8%

Therefore the probability of The voter had a college degree and voted in the last presidential election will be 8%

B. Calculation to determine the probability of The voter did not have a college degree and did not vote in the last presidential election.

P =396/1000

P=0.396*100

P=39.6%

Therefore the probability of The voter did not have a college degree and did not vote in the last presidential election will be 39.6%

C. Calculation to determine the probability if The voter voted in the last presidential election.

P = 584/1,000

P=0.584*100

P=58.4%

Therefore the probability if The voter voted in the last presidential election will be 58.4%

D. Calculation to determine the probability if The voter did not vote in the last presidential election.

P = 416/1000

P=0.416*100

P=41.6%

Therefore the probability if The voter did not vote in the last presidential election will be 41.6%

A rectangular deck has a length of 12 feet and a perimeter of 36 feet. What is the deck's width and area?
aniked [119]

Answer:

  • Deck's width is 6 feet.
  • The area is 72 sq. ft.

Step-by-step explanation:

First, label it out:

  • Length: 12 ft.
  • Width: ?
  • Area: ?
  • Perimeter: 36 ft.

Then, we add up 12 twice (Since the length is on 2 sides):

  • 12 + 12 = 24
  • 36 - 24 = 12
  • 12 - ? = ?

Now, we write down a 6 in the ?:

  • 12 - 6 = 6.

Width = 6.

We are not done!

Now, we have to solve for area.

  • 12 * 6
  • = 72
<h2>Answers are:</h2><h2>Area = 72 sq. ft.</h2><h2>Width = 6 ft.</h2>

Find all real zeros of the function f(x) = 12<br> a. 5,7<br> b. 12<br> c.1<br> d.none
oksian1 [2.3K]

Answer: hi there! your answer should be d let me tell you why...

This function has no zeros.

This is because f(x)=12, meaning no matter the x value, the y value is always 12. If the y value is always 12, it is never 0, and therefore has no zeros.

hope this help have a great day! let me know if im right or wrong plz!:)
